DETAILED DESCRIPTION

The following detailed description of example implementations refers tothe accompanying drawings. The same reference numbers in differentdrawings may identify the same or similar elements.

A network service provider may want to determine information related toan object (e.g., a file entering a network associated with the networkservice provider, a file on a device connected to the network, anexecutable file, or the like). The object may include object content(e.g., strings, phrases, sentences, error messages, dialog boxes, windowtitles, names, web addresses, network addresses, etc.) and objectmetadata (e.g., information that describes the object, such as apublisher of the object, a date of publication of the object, an objecttype, an operating system, a description of the object, a versionidentifier associated with the object, etc.). The network serviceprovider may maintain and/or access a private database to determineinformation, related to objects, that may be used, for example, todetermine whether the objects appear to be malicious. However, theprivate database may be inadequate to determine the information. Forexample, the object may be too new, too obscure, etc. to be included inthe private database. Further, the private database may rely on aparticular entity to update the database, which may cause the privatedatabase to be prone to error and omission.

Implementations described herein may assist the network service providerin determining information related to an object using a public Internetsearch, rather than (or in addition to) a private database search. Anetwork security device may receive the object, and may determine objectcontent and object metadata from the object. The network security devicemay provide the object content and/or the object metadata to a searchengine device as Internet search terms. Based on the Internet searchterms, the network security device may receive Internet search resultsthat describe publicly available webpages, documents, or the like. Thenetwork security device may analyze the Internet search results todetermine Internet-based object information that describes the object.The network security device may provide and/or store the Internet-basedobject information (e.g., with other information related to the object,as part of a database of information related to objects, or the like).In this way, the network security device may determine objectinformation from the Internet, which covers a broader range of objectsthan any private database, frequently provides information related tonew (e.g., recent) objects, incorporates information provided by membersof the public, and which may provide additional insight into sources,publishers, intended uses, etc. of the object.

FIG. 1 is a diagram of an overview of an example implementation 100described herein. As shown in FIG. 1, assume that a network securitydevice receives an object. Assume further that the object includesobject content and object metadata. As shown, the network securitydevice may determine the object content and the object metadata from theobject. As further shown, assume that the network security deviceprovides the object content and the object metadata to an Internetsearch engine (e.g., by providing different strings, phrases, etc. asdifferent search terms, or the like). As shown, the network securitydevice may receive Internet search results based on the Internet searchengine performing a search based on the object content and metadata. Asfurther shown, the network security device may determine Internet-basedobject information based on the Internet search results. TheInternet-based object information may include information related to anage of the object, an origin of the object, a reputation of websitesassociated with the object (e.g., malware websites, adware websites,social media websites, blog websites, etc.), a measure of popularity ofwebsites associated with the object (e.g., based on pageviews, otherlinking websites, search result rankings, or the like), forumdiscussions of the object (e.g., a number of posts in the forumdiscussions, topics of the forum discussions, etc.), or the like. Thenetwork security device, or another device, may use the Internet-basedobject information to determine whether the object is malicious, a typeof the object, or the like.

In this way, the network security device may compile Internet searchresults based on object content and object metadata. The Internet searchresults may provide information that may be unavailable in privatedatabases due to age, obscurity, or the like. The network securitydevice may analyze the Internet search results to determineInternet-based object information, which may aid the network securitydevice and/or a network service provider, associated with the networksecurity device, in classifying and/or monitoring the object (e.g., todetermine whether the object is malicious).

In some implementations,client device 210 may receive information from and/or transmitinformation to another device in environment 200. For example, clientdevice 210 may receive an object from and/or provide an object tonetwork security device 220 (e.g., for Internet-based analysis). In someimplementations, client device 210 may receive, generate, store,process, and/or provide Internet-based object information (e.g.,Internet-based object information generated by client device 210, bynetwork security device 220, or by another device).

For example, network securitydevice 220 may include a computing device, such as a server, a mobilephone (e.g., a smart phone, a radiotelephone, etc.), a laptop computer,a tablet computer, a handheld computer, or a similar device. In someimplementations, network security device 220 may include a networkdevice, such as a gateway, a firewall, a hub, a router, or a similardevice. Network security device 220 may receive an object (e.g., anobject destined for client device 210, an object provided by clientdevice 210, or the like). Network security device 220 may determineobject content and/or object metadata from the object. In someimplementations, network security device 220 may provide the objectcontent and/or the object metadata to an Internet search engine (e.g.,for an Internet search based on the object content and/or objectmetadata). Network security device 220 may store and/or provideInternet-based object information (e.g., to client device 210 or toanother device). In some implementations, network security device 220may determine whether an object is malicious based on Internet-basedobject information, and/or may provide the Internet-based objectinformation to another device (e.g., for the other device to use todetermine whether the object is malicious).

Search engine device 230 may include one or more devices capable ofreceiving, generating, storing, processing, and/or providing Internetsearch queries and/or Internet search results. For example, searchengine device 230 may include a server, or a similar device. Searchengine device 230 may receive Internet search queries from networksecurity device 220 or another device, and may determine Internet searchresults (e.g., Internet documents relevant to the Internet searchqueries) by searching the Internet based on the Internet search queries.Search engine device 230 may generate a ranked list of the Internetsearch results (e.g., based on a ranking algorithm) and may provide theranked list of the Internet search results to network security device220 or another device.

Network 240 may include one or more wired and/or wireless networks. Forexample, network 240 may include a cellular network (e.g., a long-termevolution (LTE) network, a 3G network, a code division multiple access(CDMA) network, etc.), a public land mobile network (PLMN), a local areanetwork (LAN), a wide area network (WAN), a metropolitan area network(MAN), a telephone network (e.g., the Public Switched Telephone Network(PSTN)), a private network, an ad hoc network, an intranet, theInternet, a fiber optic-based network, a cloud computing network, or thelike, and/or a combination of these or other types of networks.

In practice, there may be additional devicesand/or networks, fewer devices and/or networks, different devices and/ornetworks, or differently arranged devices and/or networks than thoseshown in FIG. 2. Furthermore, two or more devices shown in FIG. 2 may beimplemented within a single device, or a single device shown in FIG. 2may be implemented as multiple, distributed devices. Additionally, oralternatively, a set of devices (e.g., one or more devices) ofenvironment 200 may perform one or more functions described as beingperformed by another set of devices of environment 200.

FIG. 3 is a diagram of example components of a device 300. Device 300may correspond to client device 210, network security device 220, and/orsearch engine device 230. In some implementations, client device 210,network security device 220, and/or search engine device 230 may includeone or more devices 300 and/or one or more components of device 300. Asshown in FIG. 3, device 300 may include a bus 310, a processor 320, amemory 330, a storage component 340, an input component 350, an outputcomponent 360, and a communication interface 370.

Bus 310 may include a component that permits communication among thecomponents of device 300. Processor 320 is implemented in hardware,firmware, or a combination of hardware and software. Processor 320 mayinclude a processor (e.g., a central processing unit (CPU), a graphicsprocessing unit (GPU), an accelerated processing unit (APU), etc.), amicroprocessor, and/or any processing component (e.g., afield-programmable gate array (FPGA), an application-specific integratedcircuit (ASIC), etc.) that interprets and/or executes instructions.Memory 330 may include a random access memory (RAM), a read only memory(ROM), and/or another type of dynamic or static storage device (e.g., aflash memory, a magnetic memory, an optical memory, etc.) that storesinformation and/or instructions for use by processor 320.

Storage component 340 may store information and/or software related tothe operation and use of device 300. For example, storage component 340may include a hard disk (e.g., a magnetic disk, an optical disk, amagneto-optic disk, a solid state disk, etc.), a compact disc (CD), adigital versatile disc (DVD), a floppy disk, a cartridge, a magnetictape, and/or another type of computer-readable medium, along with acorresponding drive.

Input component 350 may include a component that permits device 300 toreceive information, such as via user input (e.g., a touch screendisplay, a keyboard, a keypad, a mouse, a button, a switch, amicrophone, etc.). Additionally, or alternatively, input component 350may include a sensor for sensing information (e.g., a global positioningsystem (GPS) component, an accelerometer, a gyroscope, an actuator,etc.). Output component 360 may include a component that provides outputinformation from device 300 (e.g., a display, a speaker, one or morelight-emitting diodes (LEDs), etc.).

Communication interface 370 may include a transceiver-like component(e.g., a transceiver, a separate receiver and transmitter, etc.) thatenables device 300 to communicate with other devices, such as via awired connection, a wireless connection, or a combination of wired andwireless connections. Communication interface 370 may permit device 300to receive information from another device and/or provide information toanother device. For example, communication interface 370 may include anEthernet interface, an optical interface, a coaxial interface, aninfrared interface, a radio frequency (RF) interface, a universal serialbus (USB) interface, a Wi-Fi interface, a cellular network interface, orthe like.

Device 300 may perform one or more processes described herein. Device300 may perform these processes in response to processor 320 executingsoftware instructions stored by a computer-readable medium, such asmemory 330 and/or storage component 340. A computer-readable medium isdefined herein as a non-transitory memory device. A memory deviceincludes memory space within a single physical storage device or memoryspace spread across multiple physical storage devices.

Software instructions may be read into memory 330 and/or storagecomponent 340 from another computer-readable medium or from anotherdevice via communication interface 370. When executed, softwareinstructions stored in memory 330 and/or storage component 340 may causeprocessor 320 to perform one or more processes described herein.Additionally, or alternatively, hardwired circuitry may be used in placeof or in combination with software instructions to perform one or moreprocesses described herein. Thus, implementations described herein arenot limited to any specific combination of hardware circuitry andsoftware.

The number and arrangement of components shown in FIG. 3 are provided asan example. In practice, device 300 may include additional components,fewer components, different components, or differently arrangedcomponents than those shown in FIG. 3. Additionally, or alternatively, aset of components (e.g., one or more components) of device 300 mayperform one or more functions described as being performed by anotherset of components of device 300.

FIG. 4 is a flow chart of an example process 400 for determiningInternet-based object information based on object content and/or objectmetadata. In some implementations, one or more process blocks of FIG. 4may be performed by network security device 220. In someimplementations, one or more process blocks of FIG. 4 may be performedby another device or a set of devices separate from or including networksecurity device 220, such as client device 210 and/or search enginedevice 230.

As shown in FIG. 4, process 400 may include receiving an object that isassociated with object content and/or object metadata (block 410). Forexample, network security device 220 may receive an object that isassociated with object content and/or object metadata. In someimplementations, network security device 220 may receive the object fromclient device 210 (e.g., based on client device 210 detecting apotential threat associated with the object, based on client device 210providing the object automatically without user input, based on clientdevice 210 receiving a user input to provide the object, or the like).In some implementations, network security device 220 may receive anobject destined for client device 210. For example, network securitydevice 220 may act as a gateway and/or firewall for client device 210,and may intercept the object en route to client device 210. Networksecurity device 220 may use the object content and/or the objectmetadata to determine Internet-based object information that describesthe object, which may aid network security device 220 in determining arisk level, an origin, or other information related to the object.

An object may include an executable file (e.g., a Windows executablefile (EXE), a Windows script file (WSF), etc.), a web page object (e.g.,a hypertext markup language (HTML) document, etc.), a text object (e.g.,a Microsoft Word document (DOC), a plain text file (TXT)), a page layoutobject (e.g., a portable document format file (PDF), a picture file(PCT)), a compressed object (e.g., a zipped file (ZIP), a WinRARcompressed archive (RAR), etc.), or another type of object.

The object content may include one or more characters, strings, phrases,sentences, or the like, that may be stored in and/or referenced by theobject. For example, the object content may include a title bar of awindow included in the object, an error message included in and/orprovided by the object, a text document included in the object, an imageand/or a description of the image included in the object, an audioobject (e.g., a transcription of the audio object, informationassociated with the audio object, or the like), a network address (e.g.,an Internet Protocol (IP) address, or the like, that is included in theobject and/or that is contacted by the object upon execution), a webaddress (e.g., that is included in the object and/or that is contactedby the object upon execution), or the like. The object metadata mayinclude information that describes the object. For example, the objectmetadata may include information that describes a time and/or date ofcreation, an author, a publisher, a location of creation, a networkaddress and/or domain name associated with the location of creation, adescription of the object, a version of the object, or the like.

As further shown in FIG. 4, process 400 may include determining theobject content and/or the object metadata (block 420). For example,network security device 220 may determine the object content and/or theobject metadata. Network security device 220 may determine the objectcontent and/or the object metadata to search the Internet for Internetsearch results for determining Internet-based object information. Insome implementations, another device (e.g., client device 210, or thelike) may determine the object content and/or the object metadata.

In some implementations, network security device 220 may perform astatic analysis to determine the object content and/or the objectmetadata from an inert object (e.g., without executing and/or openingthe object). For example, network security device 220 may perform astatic analysis by parsing, examining, and/or reading the object. Insome implementations, network security device 220 may attempt todetermine object content information and/or object metadata from theinert object based on an object type. For example, if an object is asuspicious executable, network security device 220 may not execute thesuspicious executable (e.g., for security reasons), and may attempt todetermine the object content and/or the object metadata by performing astatic analysis. Additionally, or alternatively, network security device220 may attempt to determine the object content and/or the objectmetadata from an inert object if network security device 220 detectsthat the object is unencrypted. In this way, network security device 220may attempt to determine object content and/or object metadata from aninert object, which may improve security and/or allow network securitydevice 220 to determine Internet-based object information withoutexecuting and/or opening the object.

In some implementations, network security device 220 may determine theobject content and/or the object metadata by opening and/or executingthe object. For example, assume that network security device 220 failsto determine object content and/or object metadata from an inert object(e.g., based on the inert object being encrypted, obfuscated, or thelike). In that case, network security device 220 may open and/or executethe object. Network security device 220 may determine the object contentand/or the object metadata after opening and/or executing the object.For example, network security device 220 may determine a network addressand/or a web address (e.g., web addresses with which the objectcommunicates), a publisher of the object, a type of the object, an errormessage, a title text, a dialog box, etc. that the object causes to bedisplayed, or the like. In some implementations, network security device220 may open and/or execute the object in a secure, compartmentalized,and/or actively monitored location (e.g., in memory) to minimize impacton network security device 220 that opening and/or executing the objectmay cause. In this way, network security device 220 may determine objectcontent and/or object metadata by opening and/or executing the object,which may aid network security device 220 in determining object contentand/or object metadata from obfuscated and/or encrypted objects and/orin determining network addresses and/or web addresses with which theobject communicates.

In some implementations, the object metadata may include a messagedigest related to the object. A message digest may include a hash valuethat is generated based on the object. In some implementations, networksecurity device 220 may generate the message digest using a messagedigest algorithm, such as a Message Digest 5 (MD5) algorithm, a SecureHash Algorithm, or the like. Network security device 220 may cause oneor more Internet searches to be performed based on the object metadata,which may allow network security device 220 to determine informationrelated to the object and associated with the message digest.

As further shown in FIG. 4, process 400 may include causing one or moreInternet searches to be performed, based on the object content and/orthe object metadata, to determine Internet search results (block 430).For example, network security device 220 may cause one or more Internetsearches to be performed, based on the object content and/or the objectmetadata, to determine Internet search results. In some implementations,network security device 220 may submit the object content and/or objectmetadata to search engine device 230 (e.g., a search engine device 230associated with Google, Yahoo, Bing, DuckDuckGo, or the like) for theInternet search. Network security device 220 may cause the one or moreInternet searches to be performed to determine Internet search resultsfor analysis. In some implementations, network security device 220 mayperform the Internet search locally.

In some implementations, network security device 220 may cause anInternet search to be performed based on a particular string. Forexample, assume that object content includes a first string, a secondstring, and a third string. In some implementations, network securitydevice 220 may cause three Internet searches to be performed (e.g., maycause an Internet search to be performed based on each of the threestrings). In some implementations, network security device 220 may causean Internet search to be performed based on a combination of the threestrings (e.g., based on the first string and the second string incombination, based on all three strings in combination, etc.).

In some implementations, network security device 220 may determineand/or generate Internet search queries based on the object contentand/or the object metadata. For example, network security device 220 mayparse the object content and/or the object metadata into strings for useas Internet search queries, may generate keywords as Internet searchqueries based on the object content and/or the object metadata, or thelike. As another example, network security device 220 may generate anInternet search query based on a particular message, title, dialog box,or the like, included in the object content, and/or based on aparticular publisher name, object type, object description, or the like,included in the object metadata. In some implementations, networksecurity device 220 may generate Internet search queries based on acombination of the object content and/or the object metadata. Forexample, network security device 220 may generate an Internet searchquery that includes information corresponding to a title of the object,a publisher of the object, and/or a version identifier associated withthe object. In this way, network security device 220 may generateInternet search queries based on the object content and/or the objectmetadata, which may improve accuracy of the Internet-based objectinformation.

In some implementations, network security device 220 may cause theInternet search to be performed automatically without user input. Forexample, based on determining the object content and/or the objectmetadata, network security device 220 may automatically cause Internetsearches to be performed based on the object content and/or the objectmetadata.

In some implementations, network security device 220 may provide asearch query to search engine device 230 for Internet searching. Searchengine device 230 may perform an Internet search based on the searchquery. In some implementations, search engine device 230 may return alist of search results corresponding to Internet documents that havebeen identified, by search engine device 230, as relevant to the searchquery. Based on the list of search results, and based on the Internetdocuments corresponding to the list of search results, network securitydevice 220 or another device may determine Internet-based objectinformation that describes an object associated with the search query.

As further shown in FIG. 4, process 400 may include analyzing theInternet search results to determine Internet-based object information(block 440). For example, network security device 220 may analyze theInternet search results to determine Internet-based object information.The Internet-based object information may describe an origin of theobject, a risk rating associated with the object, a suspected type ofthe object (e.g., a Trojan horse type, a malware type, an adware type, avirus type, a ransomware type, a social media type, a restricted contenttype, etc.), or other information.

In some implementations, network security device 220 may apply a set ofrules to analyze the Internet search results. The set of rules mayindicate a conclusion for network security device 220 to determine basedon a characteristic of an Internet search result. For example, a firstset of top-ranked Internet search results originating from a malwarewebsite may indicate that an object associated with the first set ofInternet search results is a malware object. As another example, asecond set of top-ranked Internet search results originating from awell-known word processor technical support forum may indicate that anobject associated with the second set of Internet search results isrelated to word processing.

In some implementations, the set of rules may prescribe rules todetermine a measure of credibility of Internet search results. Forexample, some Internet search results may be more important than otherInternet search results for determining Internet-based objectinformation. The set of rules may prescribe one or more rules todetermine which Internet search results are most important fordetermining Internet-based object information, as described below. Inthis way, network security device 220 may determine a credibility ofInternet search results based on a set of rules, which may improveaccuracy and relevance of the Internet-based object information.

In some implementations, the set of rules may determine Internet-basedobject information and/or a measure of credibility based on an age of anInternet search result. For example, a more recently published Internetsearch result may indicate that information included in the Internetsearch result is more current, and may be afforded more credibility bynetwork security device 220. As another example, an old Internet searchresult may be afforded less credibility by network security device 220(e.g., based on the information possibly being outdated or inaccurate).In this way, network security device 220 may determine a measure ofcredibility based on an age of an Internet search result, which mayallow network security device 220 to improve accuracy of Internet-basedobject information for recently created and/or old objects.

In some implementations, the set of rules may determine Internet-basedobject information based on a measure of popularity of an Internetsearch result. For example, network security device 220 may assign morecredibility to an Internet search result that receives millions of hitsper day than to an Internet search result that receives hundreds of hitsper day. In this way, network security device 220 may improve accuracyof Internet-based object information by accounting for increasedaccuracy and/or reliability of a more popular Internet document over aless popular Internet document.

In some implementations, the set of rules may determine Internet-basedobject information based on a reputation associated with an Internetsearch result (e.g., based on a reputation score stored by a server,based on other webpages that link to the webpage, or the like). Forexample, assume that network security device 220 causes an Internetsearch based on an object and receives an Internet search result of awebpage with a reputation of being associated with malware. Networksecurity device 220 may determine Internet-based object information thatindicates that the object is possibly malware (e.g., based on thewebpage being associated with malware). As another example, assume thatnetwork security device 220 receives an Internet search result of areputable community support page for a word processor. Network securitydevice 220 may determine Internet-based object information thatindicates that that an object associated with the Internet search resultis possibly related to word processing, and is possibly not malicious.In this way, network security device 220 may improve accuracy ofInternet-based object information by accounting for reputations ofInternet search results in order to determine whether the Internetsearch results are associated with malicious webpages, or the like.

In some implementations, the set of rules may determine Internet-basedobject information based on a forum discussion within an Internet searchresult. For example, network security device 220 may evaluate areputation of the forum, a quantity of responses to the forumdiscussion, a topic of the forum discussion, content of the forumdiscussion, or the like. In some implementations, network securitydevice 220 may search for keywords, key phrases, etc., in the forumdiscussion to determine Internet-based object information based on theforum discussion. In this way, network security device 220 may determineInternet-based object information based on forum discussions, which mayallow network security device 220 to determine additional informationbased on discussions of the object that occur between persons.

In some implementations, network security device 220 may combinemultiple criteria to determine Internet-based object information. Forexample, network security device 220 may determine the Internet-basedobject information based on a combination of a reputation associatedwith Internet search results, a measure of popularity of the Internetsearch results, and/or an age associated with the Internet searchresults. In some implementations, network security device 220 maydetermine Internet-based object information based on a weightedcombination of criteria. For example, network security device 220 mayassign a greater relative weight to a reputation associated withInternet search results, and may assign a lesser relative weight to anage associated with the Internet search results, or vice versa. Networksecurity device 220 may determine Internet-based object informationbased on the relative weights. In this way, network security device 220may determine Internet-based object information based on relativeweights of different criteria, which may allow network security device220 to emphasize certain criteria when determining the Internet-basedobject information.

In some implementations, network security device 220 may determine aclassification of the object. For example, network security device 220may determine Internet-based object information, and may determine aclassification based on the Internet-based object information. Theclassification may indicate that the object is unsafe (e.g., a malwareprogram and/or file, a spyware program and/or file, an adware programand/or file, a virus, etc.), that the object is safe (e.g., a safeprogram and/or file), a particular category of file (e.g., a socialmedia file, a restricted category of file, a malware file, a filecontaining sensitive information, etc.), or the like. In someimplementations, network security device 220 may determine a probabilityassociated with a classification. For example, network security device220 may determine a probability that an object is unsafe, safe, belongsto a particular category, or the like, based on Internet-based objectinformation.

In some implementations, network security device 220 may apply a machinelearning algorithm to analyze Internet search results. The machinelearning algorithm may analyze Internet search results that are based onknown objects to generate rules for a predictive model for determiningInternet-based object information that describes unknown objects. Forexample, network security device 220 may provide a set of knownmalicious and/or non-malicious objects and Internet search resultsassociated with the set of known malicious and/or non-malicious objects.The machine learning algorithm may generate rules for a predictive modelbased on the set of known malicious and/or non-malicious objects and theInternet search results. The machine learning algorithm may then use thepredictive model to determine Internet-based object information forunknown objects, to predict that the unknown object is malicious, topredict that the unknown object is non-malicious, to predict a type ofcontent associated with the unknown object, or the like. The abovedescription of rules related to Internet search results are not intendedto be exhaustive of possible implementations. Other rules and/ortechniques may be used to determine the Internet-based objectinformation, such as a mathematical analysis technique, a statisticalanalysis technique, or the like.

As further shown in FIG. 4, process 400 may include storing and/orproviding the Internet-based object information (block 450). Forexample, network security device 220 may store and/or provide theInternet-based object information. In some implementations, networksecurity device 220 may store the Internet-based object informationlocally. Additionally, or alternatively, network security device 220 mayprovide the Internet-based object information to another device (e.g.,client device 220, a server, a cloud-based storage service, a machinelearning device, an analysis device, or the like).

In some implementations, network security device 220 or another device(e.g., a machine learning device, an analysis device, etc.) maydetermine whether an object is malicious based on the Internet-basedobject information. For example, network security device 220 maydetermine a probability that an object is malicious based onInternet-based object information, and may determine whether the objectis malicious based on the probability. In some implementations, networksecurity device 220 may provide the Internet-based object information toanother device (e.g., a machine learning device, an analysis device, orthe like), for the other device to determine whether the object ismalicious. In this way, network security device 220 may determineInternet-based object information to determine whether an object ismalicious, which may improve accuracy of the determination of whetherthe object is malicious.

In some implementations, network security device 220 may drop the objectbased on determining that the object is malicious. For example, networksecurity device 220 may determine that the object is malicious, and maydelete the object (e.g., rather than providing the object to adestination of the object). In this way, network security device 220 maydrop a malicious object, which may prevent the malicious object fromcompromising a destination device (e.g., client device 210) and/orproviding information from a compromised device to a malicious party.

In some implementations, network security device 220 may quarantine theobject based on determining that the object is malicious. For example,network security device 220 may store the object in safe, isolatedmemory (e.g., for further analysis). By quarantining the object, networksecurity device 220 may allow a network administrator to analyze theobject, which may improve network security with respect to maliciousobjects.

In some implementations, based on determining that the object ismalicious, network security device 220 may send a notification to clientdevice 210 in association with the object. For example, network securitydevice 220 may provide a warning to client device 210, indicating thatthe object may be malicious and to install and/or execute the object atthe risk of client device 210. In this way, network security device 220may ensure that a user of client device 210 is aware of risks associatedwith executing a potentially malicious object, while still allowingclient device 210 to execute the object if the user desires.

In some implementations, network security device 220 may execute theobject in a sandbox based on determining that the object is malicious.For example, network security device 220 may execute the object in asecure, compartmentalized, and/or actively monitored location. Networksecurity device 220 may actively monitor the execution of the maliciousobject, which may provide additional information for network securitydevice 220 to use to detect and control malicious objects.

In some implementations, network security device 220 may add informationrelated to the object to a predictive model based on determining thatthe object is malicious. For example, network security device 220 maymodify rules for a predictive model based on the object (e.g., based oncharacteristics of the object, based on actions performed by the objectwhen executed, etc.). In this way, network security device 220 mayupdate a predictive model based on determining that an object ismalicious, which may improve accuracy of the predictive model indetermining whether other objects are malicious.

In some implementations, network security device 220 may add informationrelated to the object to a blacklist based on determining that theobject is malicious. For example, network security device 220 maymaintain and/or access a blacklist to determine whether objects aremalicious. Based on determining that the object is malicious, networksecurity device 220 may add information that describes and/or is relatedto the object to the blacklist. In this way, network security device 220may improve coverage of a blacklist based on Internet-based objectinformation, which may improve accuracy of the blacklist for determiningwhether other objects are malicious.

In some implementations, network security device 220 may notify anetwork administrator that the object is malicious based on determiningthat the object is malicious. For example, network security device 220may provide a message and/or the object to a network administrator basedon determining that the object is malicious. This may be useful when theobject originates from within the network and/or is frequentlyencountered by network security device 220. In this way, networksecurity device 220 may notify a network administrator of a maliciousobject, which may allow the network administrator to take action to warna user, or the like.

In some implementations, network security device 220 may perform acombination of the above actions based on determining that the object ismalicious. For example, network security device 220 may notify a networkadministrator that an object is malicious, quarantine the object forfurther analysis, and/or execute the object in a sandbox to perform thefurther analysis. In some implementations, network security device 220may perform a combination of the above actions based on a configuration(e.g., a configuration provided by a network administrator, anautomatically determined configuration, or the like). In this way,network security device 220 may perform a combination of actions basedon a configuration, which may allow, for example, a networkadministrator to customize protection offered by network security device220.

Although FIG. 4 shows example blocks of process 400, in someimplementations, process 400 may include additional blocks, fewerblocks, different blocks, or differently arranged blocks than thosedepicted in FIG. 4. Additionally, or alternatively, two or more of theblocks of process 400 may be performed in parallel.

FIGS. 5A-5D are diagrams of an example implementation 500 relating toexample process 400 shown in FIG. 4. FIGS. 5A-5D show an example ofdetermining Internet-based object information based on object contentand/or object metadata.

As shown in FIG. 5A, and reference number 505, network security device220 may receive an object (e.g., shown as Notatrojan.exe). Assume thatnetwork security device 220 receives the object en route to clientdevice 210 (e.g., as indicated by the dotted arrow). As shown byreference number 510, network security device 220 may determine objectinformation for the object (e.g., object content, object metadata, orthe like).

As shown in FIG. 5B, and by reference number 515, network securitydevice 220 may determine object content and object metadata for theexecutable object. Assume that network security device 220 performs astatic analysis to determine the object content and the object metadatafrom the executable object. Additionally, or alternatively, networksecurity device 220 may execute the executable object to determine theobject content and the object metadata. As shown by reference number520, network security device 220 may successfully determine the objectcontent (e.g., shown as a first string of “Error: runtime exception1231546,” a second string of “Installing Notatrojan.exe,” and a thirdstring of “Are you sure you want to quit installing Notatrojan.exe?”).

As shown by reference number 525, network security device 220 maydetermine object metadata for the executable object. Here, networksecurity device 220 determines object metadata that identifies apublisher (e.g., Crackers, Inc.), a date of publication (e.g., Mar. 29,2014), an object type (e.g., executable), an operating system (e.g.,Windows), an object description (e.g., “This is not a trojan”), and anobject version (e.g., version 6.12). As further shown, assume thatnetwork security device 220 processes the object content the objectmetadata to generate search queries.

As shown in FIG. 5C, and by reference number 530, network securitydevice 220 may provide the object content and the object metadata (orkeywords generated based on the object content and the object metadata)to an Internet search engine (e.g., search engine device 230) as searchqueries. Assume that the Internet search engine receives the searchqueries and performs Internet searches based on each of the searchqueries. As shown by reference number 535, network security device 220may receive Internet search results based on the Internet searchqueries. As shown, the Internet search results may include links towebpages (e.g., hackers-r-us.com, malwarecentral.com, badwebsite.org,etc.) and/or links to forum conversations (e.g., “Best viruses outthere?” and an indication of fifty replies to the conversation, and“Watch out for this virus, Notatrojan.exe!” and an indication of tenreplies).

As shown in FIG. 5D, and by reference number 540, network securitydevice 220 may analyze the Internet search results. Assume that networksecurity device 220 analyzes the Internet search results based on a setof rules to determine conclusions related to the executable object. Asshown by reference number 545, network security device 220 may determinea set of conclusions related to the Internet search results and theexecutable object (e.g., may determine that the top Internet searchresults are malware websites, may determine that forum posts related tothe executable object indicate that the executable object is malware,and may determine that recently created Internet search results indicatethat the executable is malware). As shown by reference number 550,network security device 220 may determine that the executable object ismalicious. Assume that network security device 220 determines that theexecutable object is malicious based on the conclusions and based on theInternet-based object information. As further shown, network securitydevice 220 may store the Internet-based object information and theconclusions. In some implementations, network security device 220 mayperform one or more remedial actions based on determining that theexecutable object is malicious.

As indicated above, FIGS. 5A-5D are provided merely as an example. Otherexamples are possible and may differ from what was described with regardto FIGS. 5A-5D.

In this way, the network security device may compile Internet searchresults based on object content and object metadata. The Internet searchresults may provide information that may be unavailable in privatedatabases due to age, obscurity, or another reason. The network securitydevice may analyze the Internet search results to determineInternet-based object information, which may aid the network securitydevice and/or a network provider that provides the network securitydevice in classifying and/or monitoring an object.
